Abstract
A box of a koto relates to improvement of a box structure utilized as a koto resonance chamber. Wood sound can be reduced, and simultaneously, the volume of the resonance chamber can be expanded. The box of the koto comprises a panel, a bottom plate, an outer koto edge and an inner koto edge, and on the cross section of the box, acute angles are respectively formed between the outer koto edge and the bottom plate and between the inner koto edge and the bottom plate. After the certain angles are formed between the outer koto edge and the bottom plate and between the inner koto edge and the bottom plate, the section of the box is trapezoidal, on the one hand, the inner space of the box is enlarged, and on the other hand, panel redundant vibration absorbing ability of the two koto edges is increased due to the fact that angles among the two koto edges and the panel are increased. If thicknesses of individual positions of the panel are not reasonable so as to cause wood sound, the two koto edges can absorb 'vibration of wood sound' by the aid of a technical means, and accordingly the effect of reducing the wood sound is achieved. After utilizing a modern design means, the box adventurously breaks through a traditional koto structure system, and has clear, bright, graceful and vacant tone.
Description
Technical field
The utility model relates to Chinese traditional folk music device Zheng, relates in particular to the improvement of doing the body structure of Zheng resonant tank to double.
Background technology
The Zheng resonant tank is big, is equipped with post on the panel, and the vibration of string is passed to panel through the zither post, and then passes through the effects such as reflection of resonant tank, obtains or clear and melodious bright or dense full musical sound.In history in the repeatedly improvement to Zheng; Repeatedly improvement was being arranged aspect the Zheng body structure, mainly was to increase casing volume, change box shape technological means such as (like " a kind of Zheng, 200520045319.2 " of Patent Office of State Intellectual Property Office bulletin).The artificial Zheng volume that increases of invention is arranged, also proposed to be provided with the technological means of portable plate at box bottom.
In any case but improve, obtain the good zither of a tool and be the very thing of difficulty, reach " execute action is anxious, zither zither so also ", sound is loud and sonorous loud and clear, the effect that intense and soft melody can both show has very big contingency.This needs the Zheng wright of experience, the manufacturing materials that also need obtain on the other hand on the one hand.Saying that from the structure angle Zheng cabinet panel is the xsect arch, is the high pitch string near what be provided with on player's one side panel (interior zither limit), and opposite side is a bass string.This just requires panel on xsect, not only will be arch, and also difference to some extent of thickness, otherwise makes part zither string " wooden sound " in performance, occur easily.Nonetheless, the zither that experienced wright manufactures meticulously, still have the wooden sound of appearance of a small amount of string phenomenon (comprise service time permanent after, water percentage changes the wooden sound that produces).To this; The inventor discovers that all the time, the interior zither limit of Zheng casing all is vertically disposed with base plate with outer zither limit; Panel receives the string vibration of zither post conduction, and the vibration transmissibility by panel imports the vibration of string into cabinets cavity (resonant tank) sounding on the one hand; The inside and outside zither limit of supported on both sides panel is because vertical with base plate on the other hand, and the ability that makes absorption panel redundancy vibrate reduces.This moment if wooden sound phenomenon can in performance, embody.
The utility model content
The utility model has improved a kind of ability and has reduced, reduced wooden sound to above problem, can also enlarge the casing of the Zheng of resonant tank volume simultaneously.
The technical scheme of the utility model is: comprise panel, base plate, outer zither limit and interior zither limit, zither limit and interior zither limit be the acute angle setting with base plate respectively at the xsect of said casing outside the above.
The angle of said outer zither limit and base plate is greater than the angle of zither limit in said and base plate.
The angle of said outer zither limit and base plate is 72-88 °, and the angle of said interior zither limit and base plate is 60-80 °.
Said casing is the arched arc towards top in the longitudinal direction.
After the outer zither limit of the utility model, interior zither limit form certain angle with base plate respectively; Make the casing cross section be trapezoidal; Its inner space becomes big on the one hand, on the other hand owing to angle between two zither limits and the panel strengthens, makes two zither limits absorb the ability increase of the redundant vibration of panel.Like this,, possibly cause wooden sound, also can utilize two zither limits to absorb " vibration of wooden sound ", to reach the effect of minimizing, the wooden sound of reduction through the technological means of the utility model if indivedual positions plate thickness is unreasonable.After the present invention incorporates the modernization design means, traditional Zheng structure shape system has been carried out bold breakthrough, made the Zheng of the utility model have clear bright, elegant free and natural tone color.

Fig. 1 is the structural representation of the utility model,
Fig. 2 is an A-A diagrammatic cross-section among Fig. 1,
Fig. 3 is the vertical view of Fig. 1,
1 is casing among the figure, the 2nd, and outer zither limit, the 3rd, interior zither limit, the 4th, base plate, the 41st, sound hole, the 5th, panel, the 6th, zither post.
Embodiment
Shown in Fig. 1-3; The casing 1 of the utility model Zheng comprises panel 5, base plate 4, outer zither limit 2 and interior zither limit 3; On base plate 4, offer sound hole 41; On panel 5, also be provided with the zither post 6 that the zither string was supported, regulated in some being used to during use, be the acute angle setting with base plate 4 respectively with interior zither limit 3 in zither limit 2 outside the above in the cross-sectional direction of said casing 1.
In view of big, the inboard thickness of panel 5 thickness as outside is little, the angle of said outer zither limit 2 and base plate 4 is greater than the angle of zither limit in said 3 with base plate 4.
As the preferred implementation of the utility model, said outer zither limit 2 is 72-88 ° with the angle of base plate 4, and said interior zither limit 3 is 60-80 ° with the angle of base plate 4.
Said casing 1 is the arched arc towards top in the longitudinal direction.
In experiment is made, when outer zither limit 2 is chosen in 75-83 ° of scope with base plate 4 angles, not only overcome the effective of wooden sound, and the bulk strength of casing is also high.
Certainly, the utility model is not got rid of the identical technical scheme of angle angle between outer zither limit 2, interior zither limit 3 and the base plate 4, can be more convenient for like this making, and can reduce wooden sound equally.
Claims (4)
1. the casing of Zheng comprises panel, base plate, outer zither limit and interior zither limit, it is characterized in that, zither limit and interior zither limit is the acute angle setting with base plate respectively at the xsect of said casing outside the above.
